Silver always works in any condition. Although goin over silver takes 2-3 times. If you see the video, the brown its pretty see through. The funny part about makin this piece is, when i went inside the spot. I gotta climb a fence with wire on top. Its hard, yea i know. When im inside for a while, some lady walked by and ask "how do you get here?". At first i was like,. "ooo shit, im gonna get busted" but then she told me there is another way to this spot without jumping over fence. She said its not nice to do that. HAHA Thats so weird, shes trying to say "its not nice to jump a fence rather than doin illegal piece".
